more macro cleanup: AC_LIBTOOL_DLOPEN_SELF

[Ralf Wildenhues]

While working on Kean's third patch, I noticed more (harmless) bogosity:
AC_LIBTOOL_DLOPEN_SELF need only be called once, for C, not once per
tag.  Similarly with current AC_LIBTOOL_SYS_LIB_STRIP.

OK to apply to branch-1-5 and forward-port (HEAD has only the STRIP_LIB
part missing, I believe)?

Cheers,
Ralf

        * libtool.m4 (AC_LIBTOOL_LANG_C_CONFIG)
        (AC_LIBTOOL_LANG_CXX_CONFIG, AC_LIBTOOL_LANG_F77_CONFIG)
        (AC_LIBTOOL_LANG_GCJ_CONFIG):  Only call
        AC_LIBTOOL_SYS_LIB_STRIP and AC_LIBTOOL_DLOPEN_SELF in the C
        case, and without the tag argument.
